Speech recognition platforms

A system comprising:na coordination component configured to receive an audio signal generated based at least in part on sound from an environment, the sound captured by a device that includes a microphone unit and a speaker and the audio signal including speech of a user in the environment;a speech recognition component configured to perform speech recognition on the audio signal to generate speech-recognition results;a natural language understanding (NLU) component configured to: identify, for different domains, multiple intents associated with the speech of the user based at least in part on the speech-recognition results and context information associated with the speech of the user, wherein identify the multiple intents includes to provide the speech-recognition results to the different domains, and to identify the multiple intents based at least in part on named entities identified from the different domains and one or more slots filled based at least in part on the context information, and rank the multiple intents for the different domains relative to one another;a dialog component configured to select one of the domains based at least in part on the ranked intents and select one of the ranked intents that is associated with the selected domain; anda response component configured to receive an indication of the selected domain and an indication of the selected intent and cause performance of an action corresponding to the selected intent, the action including providing an audio signal for output on the speaker of the device.

A system comprising:none or more processors; andcomputer-readable media storing computer-executable instructions that, when executed by the one or more processors, cause the one or more processors to perform acts comprising:receiving an audio signal that includes speech from a user, the speech of the user received at a device that includes a speaker;retrieving context information associated with the speech, the context information based at least in part on a previous interaction between the user and the device;performing speech recognition on the audio signal to generate speech-recognition results;identifying multiple intents, for different domains, associated with the speech based at least in part on the speech-recognition results and the context information, wherein identify the multiple intents includes to provide the speech-recognition results to the different domains, and to identify the multiple intents based at least in part on named entities identified from the different domains and one or more slots filled based at least in part on the context information;selecting one of the domains based at least in part on the multiple intents for the different domains;selecting, from the multiple intents, an intent that is associated with the selected domain; andproviding an audio signal for output on the speaker of the device based at least in part on the selected intent and the selected domain.

A method comprising:nunder control of one or more computing systems configured with executable instructions,receiving an audio signal generated by a device, the audio signal including speech of a user;performing speech recognition on the speech to generate speech-recognition results;identifying, based at least in part on the speech-recognition results, first potential intents of the speech, the first potential intents being associated with a first domain;identifying, based at least in part on the speech-recognition results, second potential intents of the speech, the second potential intents being associated with a second domain, wherein identifying the first potential intents of the speech and the second potential intents of the speech include to provide the speech-recognition results to the first domain and to the second domain, and to identify the first potential intents of the speech and the second potential intents of the speech based at least in part on named entities identified from the first domain and the second domain and one or more slots filled by the first domain and the second domain;selecting the first potential intents or the second potential intents; andproviding an audio signal for output on the device based at least in part on the selecting.
